1305.07 FLOODWAYS.
   A floodway is the channel of a river or other water course and adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. The floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential. The Flood Insurance Rate Map (or Flood Hazard Boundary Map) does not designate a floodway. However, floodways may be delineated in other available sources of flood information as specified in Section 1305.04(d)(2). The following provisions apply within all delineated floodway areas:
   (a)   Prohibit encroachments, including fill, new construction, substantial improvements, and other development unless a technical evaluation demonstrates that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
   (b)   If subsection (a) hereof is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Sections 1305.05 and 1305.06.
